KOBELCO 235SR ACERA CRAWLER EXCAVATOR

Technical Description

The Kobelco 235SR ACERA is a heavy-duty hydraulic excavator designed for efficient digging and maneuverability, with an operating weight of approximately 58,870 lbs. It features a Hino J05E 4-cylinder, direct injection, water-cooled diesel engine with turbocharger and intercooler, delivering a net power output of 153 hp (114 kW) that complies with stringent emission regulations such as EU Stage IIIA and US EPA Tier III. The engine provides robust torque of around 572-592 Nm at 1600-2000 rpm, ensuring powerful performance during demanding excavation tasks. This model boasts a maximum digging depth of 21.67 feet and a maximum reach along the ground of 32.33 feet, making it suitable for a wide range of construction and earthmoving applications. Its boom and arm cylinders provide powerful digging forces, supported by a hydraulic system composed of two variable displacement pumps and one gear pump, allowing maximum discharge flows up to 220 L/min per pump and high relief valve settings (up to 37.7 MPa in power boost mode). The 235SR ACERA incorporates advanced technology such as Kobelco’s Integrated Noise Dust Reduction (iNDr) system which improves air filtration and cooling while reducing noise emissions. It includes an Intelligent Total Control System (ITCS) to optimize hydraulic performance, offering smooth control and greater breakout force. The excavator features a short rear swing radius for enhanced maneuverability in tight working spaces, alongside a robust undercarriage and heavy-duty boom and arm attachments to maximize durability and operational efficiency. Its cab is designed with ergonomic controls and safety features to reduce operator fatigue during extended use.
